PhysX SDK 2.8.4: Optimized CPU Cloth Simulation
NVIDIA PhysX 2.8.4: CPU PhysX cloth demo
In the release notes of the PhysX SDK 188.8.131.52, there is this line:
- Optimized cloth simulation on PS3, XBOX 360, PC CPU
The new PhysX SDK 2.8.4 comes with an optimized CPU cloth simulation path and is compiled with SSE2 option. Optimized CPU cloth simulation ? According to the test I did, this is true. The cloth sample shipped with PhysX SDK shows clearly the gain in performance. I tested on my dev system with a GTX 460 (R260.63) + Quad Core X 9650 @ 3.2GHz:
- PhysX 2.8.4: 443 FPS
- PhysX 2.8.3: 112 FPS

We have a gain of 4X in performance which is really nice.
The guys at gamevicio.com.br have similar results with the cloth demo.
Thanks to Zogrim for the info
